Matthew, who looked very handsome in a suit at the Harry Potterpremiere, spoke with SheKnows about the romance between his character and Luna (Evanna Lynch) in the final Potter film and how he felt about it.

“I liked it,” he said. “Obviously I think it’s terribly coincidental that Harry (Daniel Radcliffe) and Ron (Rupert Grint) marry people from high school — I know that doesn’t happen often.”

But while Matthew likes that Neville and Luna end up together, he was still very scared of her!

“Neville and Luna are both outcasts when they’re younger. It was endearing for two inspiring characters. Both come from humble beginnings, people think that they’ll never amount to anything and yet they both do,” Matthew explained. “But, Luna is a lot more scary than Voldemort, I think [laughs]. Girls in general are scarier than Voldemort. It might have been the next challenge for Neville.”
